Michael Prieß commented on KARAF-2466:
--------------------------------------
I miss the part of using system properties and enviroment variables in the
documentation.
> make it easy to access environment variables inside karaf configuration
> properties files - via ${ENV.foo}?

> Key: KARAF-2466
> URL: https://issues.apache.org/jira/browse/KARAF-2466
> Project: Karaf
> Issue Type: Improvement
> Components: karaf-core
> Reporter: james strachan
> Assignee: Jean-Baptiste Onofré
>
> when using karaf in clouds & PaaS infrastructures like OpenShift, Docker,
> OpenStack et al; its common to use environment variables to pass in
> environment specific values; then keep a single disk image. It would be nice
> if there was an easy way to reference environment variables similar to the
> ${foo.bar} syntax for accessing system properties.
> Maybe karaf should support some kind of environment variable expansion like
> {code}
> # define a property based on an env var
> foo = ${ENV.nameOfEnvVar}
> # e.g. here's the host name
> host = ${ENV.HOSTNAME}
> {code}
